Nodular lymphangitis caused by Mycobacterium marinum

Abstract

A five-year-old boy was presented to a local walk-in clinic with an infection in the area of the external malleolus of the right foot, for which amoxicillin was prescribed. Upon completion of the course of the antibiotic, the inflammation in the primary area of the infection subsided but the multiple sites of nodular lymphangitis in the surrounding area persisted. Examination of those sites lead to the identification of Mycobacterium marinum as the cause of the coinfection.
